The bulletin explained that some domestic violent extremists "motivated by the QAnon conspiracy theory" could be mobilized to action because they believe that Trump will be inaugurated on March 4 or will return to power on May 20 with the help of the USA military.
In their desperation, there has been a lot of QAnon chatter centering on March 4 in recent weeks - apparently in reference to March 4 being the original date for presidential inauguration in the Constitution.
Rioters try to break through a police barrier at the Capitol in Washington.
Acting Chief Yogananda Pittman testified Wednesday before a House subcommittee.
The U.S. Capitol Police says that it is aware of a threat by an unidentified militia group to breach the Capitol complex on Thursday. The Oath Keepers and Three Percenters are armed militia groups.
The statement differs from an advisory that was sent to members of Congress by the acting House sergeant-at-arms this week, saying Capitol Police had "no indication that groups will travel to Washington, D.C.to protest or commit acts of violence".
FBI Director Christopher Wray told lawmakers on Tuesday that the attack on the Capitol on January 6 was "domestic terrorism" - a threat which he said was "metastasizing" across the country.
A senior House Democratic leadership source told Fox News that the decision was made to cancel votes for the rest of the week "partially" due to the risks of the threat presented to lawmakers by the United States Capitol Police.
Manhattan prosecutor gets Trump tax records after long fight
No formal charges have been filed in the case. "Even then, I'm sure there will be tons of litigation about that", Citron said. Those would include communications showing how the raw data was analysed and treated in the preparation of the records.
As ABC News reports, just this week, U.S. Department of Homeland Security's Office of Intelligence and Analysis issued a confidential report to law enforcement agencies suggesting that the ongoing threat of domestic terrorism is being driven by "violent anti-government or anti-authority narratives, periods of prolonged civil unrest and conspiracy theories", and it is a trend that will likely continue into 2021 and "could escalate to include targeting of critical infrastructure".
The Senate hearing is the second about what went wrong on January 6, with national security officials face questions about missed intelligence and botched efforts to quickly gather National Guard troops that day as a violent mob laid siege to the U.S. Capitol.
"We are taking the intelligence seriously".
The warning about another potential threat to Congress comes as a date for President Biden's first address on Capitol Hill has not yet been set. March 4 is considered by some to be the "real inauguration day", though there has not been almost the amount of online chatter that occurred before January 6 from extremist groups. Five people including a police officer died in the riot.
Also, thousands of accounts that promoted the January 6 event that led to a violent storming of the US Capitol have since been suspended by major tech companies like Facebook and Twitter, making it far more hard for QAnon and far-right groups to organise a repeat.
Congress has, for now, abandoned any examination of Trump's role in the attack after the Senate acquitted him last month of inciting the riot by telling the supporters that morning to "fight like hell" to overturn his defeat.
Del. Eleanor Holmes Norton (D-D.C.), who has been pushing for removal of the fencing around the Capitol, said Wednesday that in light of the new information, the barriers and increased police presence "may have to be there right now".
"I believe that there should be additional resources assigned to their efforts to sweep for explosives, for example", he said. "And I don't know to what degree that's being done right now".
